dead battery

Monday I was all set to take the bike to work since I haven't had it out in well over a month. I anticipated the possibility of a low battery, but the battery tender should have kept it up. I went to start it and it was dead, as in 3 volts dead. It seems the extension cord got knocked out of the socket and it's been sitting for a long time with no maintenance. Without the maintenance, in the sub-freezing temps for weeks, it slowly froze and lost its charge. So I pulled the battery and brought it inside to thaw out and then tried to charge it. No luck. My battery is toast.

I am tired of having to keep it on a charger, so I did some looking around and found a Li-Ion battery for the motorcycle. It can hold a charge in the cold for up to a year, compared with weeks for a lead-acid battery. It costs twice as much as a standard lead-acid battery, but the manufacturer says ti should last 2-3x as long as the lead-acid battery does. On a motorcycle, that is 2-3 years on average so this one should last 5-6 or longer. On top of that, because of the type of battery I won't need to plug it in every night in the cold weather to keep the charge level up. They actually recommend not charging it unless it really needs to be charged. It should be here any day now. :)
